API Gateways serve as a crucial component in modern software architectures, particularly in microservices-based systems. They act as a single entry point for all API requests, simplifying the interaction between clients and backend services. By decoupling client applications from the complexities of backend microservices, API Gateways enhance API management, performance, and security. They handle various tasks such as routing requests, managing authentication, and aggregating responses from multiple services. As software systems grow in complexity, the role of API Gateways becomes increasingly vital in ensuring effective communication and integration between services and clients.
